FEM Workbench not available

[GitWyd]

Hi,

After installing FreeCAD as instructed and successfully starting it, I am unable to access the FEM workbench. Instead I am presented with the following error message:

libvtkIOXML-8.1.so.1: cannot open shared object file: No such file or directory
Traceback (most recent call last):
File "", line 45, in Initialize

Do you have an idea on how I can fix this?

Best,
Philippe

Vtk wasn't pinned the right way. Please install freecad from freecad/label/dev (0.19pre) or install a compatible vtk:

conda create -n freecad freecad qt=5.9.* -c freecad/label/def -c conda-forge
conda create -n freecad freecad vtk=8.1.* -c conda-forge

Hopefully this helps solving this issue.

Thank you for your quick response.

conda create -n freecad freecad qt=5.9.* -c freecad/label/def -c conda-forge
The above approach yielded the following error:

UnsatisfiableError: The following specifications were found to be incompatible with each other:

  - freecad -> pivy -> pyside2 -> qt[version='>=5.9.7,<5.10.0a0']
  - qt=5.9

The second line worked:
conda create -n freecad freecad vtk=8.1.* -c conda-forge

However, when I try to start FreeCAD in the newly created environment, I get the following issues at startup:

FreeCAD 0.18, Libs: 0.18R16117 (Git)

Any suggestions?

sry, I made one mistake. It's not freecad/label/def but freecad/label/dev. I hope this solves this issue.

Hi, I created an env using this command :

conda create -n freecad freecad qt=5.9.* -c freecad/label/def -c conda-forge

and I run one old FEM Macro using FreeCAD gui , in which I had CalculiX as solver, and I got this error :

FEM: CalculiX binary ccx not found in standard system binary path. Please install ccx or set path to binary in FEM preferences tab CalculiX.

could you please guide me how can I fix this? ( I tried it on both Mac and Windows)

Thanks in advance

You can install calculix via conda install calculix -c conda-forge

thanks a lot for your fast reply.

my problem is solved in windows, but in Mac I got this:

Running the Python command 'FEM_SolverRun' failed:

as I did not need the progress bar, I commented it in ccxtool.py and now it works! ( I am not sure if it is a good solution though!)

Hello, I am facing the same problem in macos. Is there any known solution to this?

What happens when you enter this into FreeCAD's Python console?
progress_bar = FreeCAD.Base.ProgressIndicator()

Does this already raise this error?

[mnesarco]

As a temporary workaround in MarzWorkbench, I have faked the ProgressIndicator for Mac:

Greetings, I'm also having this error and I tested as you say and it sure does! Any idea what's causing this? I'm also on MACos. Application was running fine yesterday, tired to import a DXF today and this happened. Any help would be much appreciated.

With the MSYS build I had the same problem and it was fixed with: FreeCAD/FreeCAD#8888
